LOFTIS WOOD, 0F NEW YORKQN. Y.

STOVE.

Specification of Letters Patent No. 4,722, dated August 28, 1846.

T 0 all whom t may concern.'

Be it known that I, LorTIs WOOD, of the city of New York, in the Stateof New York, have made certain new and useful Improvements in the Mannerof Constructing Stoves for Heating Apartments; and I do hereby declarethat the following is a full and eX- act description thereof.

In the accompanying drawings, Figure l is an elevation of my .improvedstove. Fig. 2 a vertical section through the axis thereof, and Fig. 3, ahorizontal section in the line m w of Fig. 1.

The body of this stove it will be seen is circular, and its chamber Ofcombustion A A is lined with fire brick. The part so lined is surroundedby a cylindrical casing B, B, leaving an air chamber C, C, between itand the cylindrical body D D of the interior of the stove. The airchamber or space C C is inclosed at its upper part by an annulus, or atring, which is perfor ated with holes for the admission of air.

` This inclosing annulus is covered by a second ring E E, shown mostdistinctly in Fig. 3; this ring lies loosely upon that first named andis capable of sliding around upon it, so as to constitute a register, bywhich the quantity of air admitted into the chamber C, is regulated; a,a, a, are perforations through the ring E E which correspond with thoseof the inclosing annulus below it, thereby constituting the register; I)b are projecting ears by which the ring E E may be moved around. Air mayalso be admitted into the air space C C from below by the opening of theash drawer F, Gr Gr being the ash pit. Around this, I place a number ofcurved air conductors H, usually four, that 'open into the air space C Cand admit air into it from the ash pit; two of these openings throughthe curved conductors I-I H into the space C, are dis* tinctly shown inFig. 2.

The ash drawer is made to lit very accurately and when this, and theregister E are lclosed, the stove is rendered nearly air tight. l/Vhenboth the register and the ash drawer are opened the fire will burn withgreat rapidity, andI by closing the ash drawer, and governing it by theregister it may be regulated in the most perfect manner.

There is not any grate below the fire, the part usually occupied by agrate being furnished with a solid plate I which, being hinged, may beallowed to fall when it is desiredto discharge the contents of the lirechamber into the ash pit. rIhe draft of air to feed the fire is admittedthrough lateral gratings J J Of which I usually emplo-y four. through anopening K at its top.

Having thus fully described the manner in which I construct my improvedstove for the heating Of apartments, whaty I claim therein as new anddesire to secure by Letters Patent, is-

l. The manner of arranging and combining therevolving register, the airchamber and the lateral gratings for the admission of air to the re, theair being admitted into the chamber, or-space C, C, through openings inan annular register E, Eabove said air space, and the draft from the airspace to feed the fire, being supplied thereto through four, or anyother preferred number of lateral grating J, J, in the manner set forth.

' 2. I also claim, in combination with the foregoing, the manner ofadmitting air from the ash pit into the air space C C by means of thecurved or other suitably formed air conductors I-I, leading from the ashpit into said space and governed by the opening and closing of the ashdrawer.
